Embryonic mass cells are in constant
division, making it much easier to find good examples of each phase of mitosis. The root and the stem are the best place to
look because they contain meristematic tissue that retains the ability to
divide throughout the life of the plant.
Answer: colostomy
Explanation:
Colostomy is a surgical procedure which is used to remove waste or feces from the body when the body is incapable of expelling out the waste. A stoma is the opening either created surgically or naturally present. It is the opening in the large intestine it allows the removal of the feces out of the body. The feces is drain through the rectum into the pouch of the collection device.
Answer:
c. smear preparation
a. fixation
b. application of staining dyes
Explanation:
In the bacterial specimen preparation and staining order, the first step would be Smear preparation in which the smear of bacteria is formed on the slide.
Then the bacterial smear is heat-fixed so that the smear does not get washed off during the washing process in the staining procedure. After heat fixing the bacterial smear, the dyes are applied to the bacterial smear to stain the bacterial cells.
Therefore the correct order is-
c. smear preparation
a. fixation
b. application of staining dyes
Answer:
genomic imprinting
Explanation:
Genomic imprinting is a mechanism for regulating gene expression that allows expression of only one of the parental alleles, although both alleles are functional. Unlike most genes in which expression is biallelic, genes that are subjected to this mechanism (imprinted genes) have monoalelic expression; By definition, in an imprinted loci, only one allele is active (maternal or paternal), and the inactive is epigenetically marked by histonic modification and / or methylation of cytosines.
Genomic imprinting can cause some disturbances, among them Prader-Willi syndrome, which is a genetic disorder that involves a partial deletion of chromosome 15q on the paternal chromosome.
